I call this my "junk bike." It's an SR "Semi Pro" model from early 1980's. It's well above the department-store bikes of its day, but the name "Semi Pro" is still not appropriate at all. But unlike my OCLV carbon-fiber Trek, it allows mounting a rack, and I use it to take a box to the post office, take laptop and tools to work, etc., so usually it has a trunk bag an/or pannier on the rack, and no seat bag. I also pull my trailer with it, with a lot of tools and supplies for work. However, when I took this picture, I was using it for regular riding (hence the three waterbottle cages and aerobars) until I could get the fork replaced on my Trek after the steering tube broke, the same as what happened to George Hincapie in the 2006 Paris-Roubaix race. It's the only tube in the frame & fork that's aluminum, and that's what broke. But back to this SR, which was given to me, free, over 20 years ago: It's a dog, as its frame wastes your energy. It looks pretty bad too, with dinged-up paint and lots of surface rust on the frame and fork. I've upgraded almost all of the components though, and everything works well. I don't know if it's any less likely to get stolen than the CF Trek, but it wouldn't be as great a loss.
